Daily reminder that Duplet is a dupe for brainlet. It simply doesn't work as advertised.
You can remove the shaped charge liners and it would work the same or even better, its basically Kontakt-5 with double the explosive content...
And since Ukraine has no access to advanced Uranium and Tungsten monocrystal growing techniques they have no way of testing this Duplet ERA against the actual threat. Its claimed performance is suspect at best.
(On another note I find it hilarious that the Russian 125 mm 2A82 - the original one, not the Armata version, is actually as powerful as the Ukrainian developed 140 mm Vityaz. These guys can only be way behind the Russians in metallurgy for this to happen.)
The reverse speed is again, not an issue since the T-90M has LWR that can automatically discharge smokescreens in case of an attack.
To put the things into a proper perspective, Nozh is Soviet era project.
And Duplet is doubling the Nozh up to two layers.
It was declined a further development in the SU, because they already have more perspective projects.
Nozh is brilliant on paper, and should be deadly effective against a variety of threats, including even bizarre ones like triple charged HEAT projectiles.
That nobody other than Soviets had, and still does not have
As I have said multiple times, Russkie were always notorious in creating solutions to their own medicine.
That is why we face such an overkill systems, when you combine something made to stop/intercept a Mach4 5 ton heavy and armored missile being used against some kids toy taken directly from commercials.
So what was the issue with Nozh, is that nobody could properly project the sequence of detonation - it is too much complicated. Tons of factors, most of which are impossible to simulate, will ignite it.
So in tests, it turned out that Nozh does work, however, the disturbed ignition sequence interferes with its own effectiveness, and at the end you get nothing better than K5. While being remarkably heavier.
Now we have another brilliant on paper project, consisting of doubling the Nozh layers to improve protection.
Brilliant, isn't it?
In practice, you have only doubled the mass, and doubled the interference ratio while retaining almost the same level of general effectiveness.
What is the Russian answer? Well, Relikt that is a NERA/ERA combination, and Malachit, that is a multi-stage ERA where segments detonates one by one by physics.
What Russkie have and Ukroisis don't have, is existing chemical and material bodies, that can deliver new types of materials needed to construct more effective main armor packages. I highly doubt if there is any protection increase comparing T-80UD and Bulat M, because Ukraine didn't have industry keen to improve it. I can bet that Bulat M retained the basic steel/resine/poliethylen/ceramic armor fillers at best. The difference Russkie made here is enormous. You can't beat that, and even if Duplet would work as desired in 100%, Russian base armor package is much better than the Ukrainian, making a claim about better armor package questionable at least.
Going further, Bulat uses Ukro made 2A46M1 gun named KBA-3. This gun is made with 80s technology, and is 40 years behind Russian equivalent, as lyle6 pointed out. There are huge differences in withstanding pressures, chamber volume, heat resistance, and finally, a quality of a gun itself.
To be fair, Bulat was already better than any tank the west can provide to Ukraine, and Bulat M is a light years ahead - yet does not match Russian 90Ms for sure. I would hardly call it an equivalent of 90A.
Last but not least, Ukraine is not capable of producing any ammo keen to effectively penetrate Russian tanks, and that applies not to the latest ones, but 30 y/o 90s as well. With all bells&whistles, they can operate an imported rounds that can engage 72B, and BM under some circumstances.
